I'm not sure if dental school will be similar, but I do my best studying at home. Whenever I would go somewhere to study, I would find that it's such annoyance. Either people talking loudly, eating extremely awful smelling food, I'd have to pack up my laptop and take it to the bathroom with me so it wouldn't get stolen, inevitably leaving something I needed to study at home, people wanted to talk to me, etc.
I just try my best to have an established spot at home that I only use to study. That way when I'm there, I'm in "study mode".
